    Solution:

    Given:
    The area of rectangle =528  m 2   The length of the rectangle be ‘l’ and the breadth of the rectangle be ‘b’.
    l=2b+1
    The area of rectangle = l×b  
    528=(2b+1)b
    528=2b2+b
    2b2+b-528=0
    2b2-32b+33b-528=0
    2b(b-16)+33(b-16)=0
    (2b+33)(b-16)=0
    2b+33=0 or b-16=0
    b=-332, 16
    The breadth of a rectangle is always positive.
    So, b = 16.
    The length
    2(16)+1m 33m  
    Hence, the length and breadth of the plot are 33m and 16m respectively.
    So, the correct option is 3.
